' 2 Claims. 257-131) This invention relates to improvements in air conditioners, and has particular reference to a conditioner wherein the air will be cooled or warmed depending upon the requirements; a

conditioner wherein the air will be forced through the device and through the room to be conditioned.

Another object of the invention is to produce a. device of this character that is easily installed,

one which is practically silent in operation and a device that is neat in appearance.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts'throughout the same:

Fig. 1 is a side elevation of my device having portions thereof broken away;

Fig. 2 is a top plan-view of Fig. 1;

Fig. 3 is a side elevation of Fig. 1 having portions thereof broken away;

Fig. 4 is a diagrammatic view showing my device as the same would be connected to a cooling brine tank and thermostat;

5 is'a cross sectional view of the thermo-.

Fig. 6 is a cross section taken on the line 6-8 I of Fig. 5; and

Fig. 7 is an enlarged fragmentary detail view showing the sliding contact.

In order to promote health it is advisable to maintain the temperature of the air in a room at a uniform degree. I have, therefore, produced a very simple device which will heat or cool the air and maintain the air passing through the device at a substantially uniform temperature, which temperature will be controlled by a room thermostat.

In the accompanying drawings wherein for the 40 purpose of illustration is shown a preferred embodiment of my invention, the numeral 5' designates a casing in which is located spaced. radia tor elements 6 and]. These radiator elements are of the honey-comb type, such as are generally employed in motor vehicles, and are connected together by a pipe 8. An inlet pipe 9 is connected to a-pump which is drivenby a motor l2 through a flexible connection i3. This pump receives a supply of fluid from the pipe I4, which 50 pipe is connected to an anti-freezing solution tank l8, and a check valve I! is introduced in the line to prevent any back flow of liquid. A return pipe I8 is connected to the bottom radiator 5 1 and to the tank IS. A drum is is positioned between the adjacent surfaces of the radiators 8 and I and serves to conduct air between the radiators and in this drum is positioned a motor 2| having a bladed fan 22. This arrangement is gosuchthatairwillbedrawninthrouzhthetop radiator at a point adjacent the edges thereof, will pass downwardly outside of the drum [9 through the outside portion of the radiator I, thence through the center portion of the radiator I through the drum l9 and through the v center portion of the radiator 5. By now delivering cool fluid to the radiator the air passing therethrough may be cooled, or if hot liquid is passed through the radiators, hot air will be discharged therefrom.

In order to control the operation of the motors 2| and I2, I provide a thermostat mounted in the casing 23 and consisting of an expansion chamber 24 actuating arm 26 and carrying a contact 21, which contact is adapted to engage an adjustable contact". This contact 28 is mounted upon a slider 28 (see Fig. 6). Therefore, by moving the slider-29 up or down the temperature at which the contacts are made or broken can be readily adjusted.

-It will thus be apparent that my device will perform all the objects above set forth.

It isto be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size,

' shape and arrangement 0. parts may be resorted to withoutdeparting from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim: 1. An air conditioner embodying a casing having spaced radiator elements mounted therein, means for conducting air through said elements comprising a drum having open ends contacting both of said elements, a motor driven fan positioned in said drum, whereby air may be drawn downwardly through the casing and about the sides of said drum and discharged upwardly through said drum and said radiator elements,

and a motor driven circulatory system connect ing the radiators, whereby a cooling fluid may be circulated through said radiator elements.

, 2. An air conditioning device of the class described embodying a casing, spaced radiator elements mounted in said casing, means for conducting conditioned air through said radiatcr elements comprising a drum having open ends contacting both of said elements, the outer surface of saiddrum being considerably smaller than the casing and providing down draft spaces within the casing and an updraft central portion within the drum, a motor driven fan positioned in said drum, whereby air may be drawn downwardly within the casing and outside of the drum and discharged upwardly through said radiator elements and the inside area of said drum, and a pump driven fluid circulating system for forcing a conditioned fluid through said radiator elements.
